Dielectric resonator antennas (DRAs) employ high-permittivity ceramic elements to confine and radiate electromagnetic energy without relying on metallic radiating surfaces. Their inherent low ...
Antenova claims that its antenna designs represent a step forward in small antennas. In most cases, says the company's engineering director, Roger Wise, conventional miniature antennas use radiating ...

Physicists just trapped light tighter than thought possible without using a speck of metal — a trick that could reshape the chips inside every device
A beam of light, by the rules physicists have relied on for more than a century, can only be squeezed so small. Push it into a tighter space and it simply leaks out, a constraint known as the ...
Dielectrics are materials that store energy when an external electric field stimulates the material. A common explanation for a dielectric is a material that will store additional charge when placed ...
Resonators are devices that exhibit resonance, a phenomenon where a system oscillates with greater amplitude at specific frequencies. In the context of nanotechnology, resonators are nanoscale ...
